[Configobj-develop] Self referencing variable names

[Mohanaraj G. K. <mo...@gm...>]

Hi guys,

I have been trying to come up with a config file that look as follows

--
log_dir = '/var/log'
oltp_host = localhost
olap_host = $oltp_host

[app]
log_dir = ${log_dir}/app
oltp_host = $oltp_host
olap_host = $olap_host
--
And access it with the following trivial code:

--
import configobj
from configobj import ConfigObj
configobj.DEFAULT_INTERPOLATION ='Template'
a = ConfigObj('./config.ini')
print a
--

However when i try to access it with the following code I get
 "configobj.InterpolationLoopError: interpolation loop detected in value
"log_dir". "

Looking at the code it seems to be because of the common names. I have
implemented a naive hack that will allow for params to have the same names
as their values, by ensuring that they don't end up referencing to
themselves. I realise that this is not a complete fix and there are still
cases where this will break down,  but I would just like to know what you
guys think ? I have attached the patch to this email.

Thanks
